Burp Suite Pro ignoring BurpSuitePro.vmoptions

Patrick | Last updated: Jun 28, 2018 08:27PM UTC

Hi Burp experts. Just recently I noticed that Burp is ignoring certain (or maybe all) JVM parameters inside the BurpSuitePro.vmoptions file. I'm usually working in a proxied environment. In order to download/install extensions and software updates for Burp, I added "-Dhttps.proxyHost" (an proxyPort, ofc.) parameters to the above mentioned file. In the past, this worked flawlessly, but for quite some time I didn't get notifications about new versions and also am unable to download/install extensions from inside Burp. Has anyone else noticed this and maybe also has a solution for that issue? Thank you in advance, Patrick

Hi Patrick, Thanks for letting us know about this. Burp does use the vmoptions file. However, it will not use the Java proxy settings, as it has its own HTTP stack. To use an upstream proxy, you need to configure this within Burp, in User options > Connections > Upstream Proxy Servers. Please let us know if you need any further assistance.
